Tailored for Microsoft Windows XP
The AMD Athlon XP processor offers compelling performance for running Microsoft Windows XP, as well as outstanding performance on previous versions of Windows. The raw power and robust features of the AMD Athlon XP processor enable users to make the most of multitasking and user switching capabilities offered in Windows XP. Microsoft optimized the DirectX 8.0 interface for Windows XP specifically for the AMD Athlon XP processor. The AMD Athlon XP processor's innovative QuantiSpeed architecture helps propel Windows XP application performance to a new level. To unleash the rich features found in Windows XP, AMD and Microsoft worked together to optimize applications like Media Encoder 8.0 for AMD's 3DNow! Professional technology.
AMD Athlon processors were used in the design and development of the Windows XP operating system, which helps to ensure that systems based on AMD processors offer excellent OS compatibility. AMD and Microsoft's strong working relationship dates back over a decade to the first version of Windows. Over the years, AMD processors have powered some of the most reliable PC systems for Windows applications, increasing productivity and enjoyment for end-users.
Featuring QuantiSpeed Architecture for Rapid Execution of Applications
QuantiSpeed architecture, the latest technological enhancement to the award-winning AMD Athlon processor core, provides for extra performance in the cutting-edge features users need most. At the heart of QuantiSpeed architecture is a nine-issue, superscalar, fully-pipelined core. This provides more pathways to feed application instructions into the execution engines of the core, simply allowing the processor to complete more work in a given clock cycle. Additional features of QuantiSpeed architecture include a superscalar, fully-pipelined floating point engine, hardware data prefetch, and exclusive, speculative Translation Look-aside Buffers (TLBs). Combined, these features help boost overall productivity and allow a system to boot and load applications quickly. In the end, users will enjoy an effortless computing experience.
Software applications and Internet plug-ins run lightning-fast because they are optimized to take advantage of innovative QuantiSpeed architecture and 3DNow! Professional technology, found exclusively in the AMD Athlon XP processor. AMD has generated benchmark data for the performance results of the AMD Athlon XP processors that Andersen, a global leader in professional services, has independently audited.
